With enertrace, you are able to create your devices inside the app and add information like name, icon and energy consumption to it. However, it works completely simple without socket adapter. You simply click the created device button inside of the app when you use a device. The app is made to give a feeling about energy consumption in general. It is not an accurate electricity tracker. It only gives a rough overview of the consumption and its costs. It was designed to consciously link the consumption of electricity with costs and to raise awareness of these. This makes it easier to live in an energy-saving way.
